Filter by:Androgen excess is the cardinal biochemical feature of polycystic ovary syndrome (PCOS). Serum testosterone correlates with insulin resistance in PCOS, however, there is an urgent need to improve our understanding of the association between androgens and the risk of type 2 diabetes. 11-oxygenated steroids are the predominant androgens in PCOS and correlate closely with markers of insulin resistance. The bioactive 11-oxygenated androgen 11-ketotestosterone (11KT) binds and activates the androgen receptor with equal affinity to testosterone, yet nothing is known about its impact on metabolism or glucose homeostasis Crucially, there are no data linking androgen excess with muscle glucose metabolism and the differential contribution of 11-oxygenated androgens to diabetes risk through these processes remains unknown. The investigators hypothesise the following: 1. Oral androgen exposure in women with PCOS results in distinct changes in tissue-specific insulin sensitivity and muscle energy biogenesis 2. 11-oxygenated androgen exposure exerts differential changes on the above parameters in comparison to classic androgen exposure The study has the following aims: 1. To examine the impact of oral androgen exposure on skeletal muscle insulin sensitivity and glucose disposal in women with PCOS. 2. To delineate the impact of androgen exposure on muscle mitochondrial function ex vivo in women with PCOS 3. To compare the differential impact of 11-oxygenated androgen compared to classic androgens on glucose disposal and muscle mitochondrial function The two arms will run in parallel and all participants will undergo identical investigations before and after 7 days of either DHEA or 11KA4. Investigations will include baseline arthrometric measurements muscle biopsy, two-step hyperinsulinaemic euglycaemic clamp, breath sampling. This interventional metabolic phenotyping study will probe the role of classic and 11-oxygenated androgens in metabolic dysfunction in PCOS using gold-standard in vivo metabolic phenotyping techniques. Delineating the distinct contribution of 11-oxygenated androgens, through effects on skeletal muscle biology, to the risk of T2DM is an important step in the process of determining risk of type 2 diabetes in this vulnerable cohort.
Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. It is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (also termed 'insulin resistance'). Androgens circulating in the blood in women with PCOS are comprised of classic androgens (for example testosterone), and the less-characterised 11-oxygenated androgen subclass that arises from the adrenal glands. The investigators have recently demonstrated that 11-oxygenated androgens make up the majority of circulating androgens in women with PCOS. In preliminary studies using minimally invasive adipose tissue sampling, the investigators have found that the fat tissue of women with PCOS overproduces classic androgens. This can lead directly to disturbances in the ability of fat cells to store fat effectively (lipotoxicity), resulting in insulin resistance and the consequent risk of liver damage. However, there are no published studies on in vivo androgen concentrations in the adipose tissue of women with PCOS. Furthermore, the scientific community do not have any information on whether adipose concentrations of 11-oxygenated androgens are also increased in women with PCOS. Research Questions The investigators aim to examine the metabolism of classic and 11-oxygenated androgens in detail in both circulations and in the adipose tissue of women with PCOS. The investigators will examine how precursor variants of both 11-oxygenated and classic androgens, which are converted by the body into active hormones, are broken down (metabolised) within the adipose tissue of women with PCOS. The investigators will also investigate if the 11-oxygenated androgens have a differential impact on metabolic function as compared to classic androgens. This will give important insights into the adipose tissue metabolome in women with PCOS, and how locally generated androgens impact on adipose tissue function and metabolic risk.
Polycystic Ovary Syndrome (PCOS) is associated with hyperandrogenism, hyperinsulinemia and insulin resistance starting in the perimenarchal period. Insulin resistance also increases the risk of developing glucose intolerance, type 2 diabetes, hypertension, dyslipidemia and cardiovascular disorders. Studies on adult women with PCOS show that their aerobic capacity is affected. Therefore, in this study; it was aimed to compare the physical and cardiovascular fitness levels of adolescent PCOS patients with healthy adolescents.
The development of Polycystic Ovary Syndrome has been linked to chronic low-grade inflammation (PCOS). In this context, the current study looked into the effects of aerobic exercise on IL6, TNF, and C-reactive protein (CRP) in PCOS women. This was a randomized clinical trial including 40 females diagnosed with PCOS who were between the ages of 25 and 35. The participants were divided into two groups, each with an equal number of individuals: aerobic exercise (AEM) and Metformin (M). At baseline and after 12 weeks of intervention, participants' levels of IL6, TNF, and CRP were measured.
This study evaluate the addition of PTX and ALA to clomiphene citrate in the treatment of polycystic ovary.
The purpose of this study is to investigate the effect of whole body vibration on insulin resistance in females with polycystic ovarian syndrome
This study evaluates the addition of clomiphene citrate (CC) to letrozole for the treatment of infertility in women with polycystic ovary syndrome across a course of two treatment cycles with stair step dosing of letrozole similar to standard of care. Half of the participants will receive letrozole and CC in combination, while the other half will receive letrozole alone.
The study aims to compare the efficacy of Empagliflozin or Linagliptin as an alternative to Metformin for treatment of non-diabetic patients with polycystic ovary syndrome (PCOS).
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in reproductive-aged women, affecting 6-21% (depending on the applied diagnostic criteria) of this population worldwide. PCOS is characterized by hyperandrogenism and/or chronic anovulation which can manifest with a range of symptoms (e.g., hirsutism, acne, oligomenorrhea, and infertility) and is associated with increased risk of cardiometabolic diseases, including hypertension, dyslipidemia, insulin resistance (IR), and type 2 diabetes mellitus (T2DM). Moreover, PCOS is linked to increased psychological morbidity (e.g., increased risk of stress, depression, low self-esteem, and poor body image). The exact PCOS etiology is unknown, but increased adiposity is considered pivotal. Indeed, almost 90% of women with PCOS are overweight or obese, and even moderate weight loss may result in clinically meaningful improvements in hyperandrogenism and menstrual regularity. Also, women with PCOS often have more severe IR than weight-matched women without PCOS, whilst their increased susceptibility to obesity may further exacerbate IR and the accompanying metabolic and reproductive dysfunctions. As such, women with PCOS exhibit an increased risk of impaired glucose tolerance and T2DM regardless of weight and age. Management of overweight/obese women with PCOS focuses on weight loss through regular exercise and diet, aiming to alleviate its clinical manifestations and lower the related risk of T2DM and cardiovascular disease. Fasting-induced negative energy also potently affects the hormones such as estradiol, testosterone, and leptin, and complex interactions exist between metabolic signals and ovarian steroids. However, fasting is difficult to implement. It is of great interest to develop feasible and efficacious fasting-mimicking diets (FMD) to alleviate the burden of fasting while preserving the beneficial effects of fasting. In a case study, the investigators observed that a 23-year-old female diagnosed with PCOS had her persistent cystic acne resolved after just 3 cycles of self-administered fasting-mimicking dieting. In addition, FDM induces a reduction in insulin levels, fasting glucose, BMI, decreased adiposity, and inflammation rates. The investigators hypothesize that a specially designed FMD will induce physiological changes similar to prolonged fasting and will decrease risk factors associated with metabolic syndrome and alleviate symptoms of PCOS.
